Chemical and radiological sample results
MS0060042 , Symonds Water Association
25 of the 58 analytes this system has been tested for have been detected at least once, across 184 samples on record.
The other 33 were tested for and never found. An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.
Across all 184 samples on record, detections range from October 18, 1993 to December 16, 2025. These figures cover the whole record; the list of samples further down is narrowed.
What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.
What has been detected, ever
Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

The most recent samples, result by result
The table below lists 1–10 of 12 samples, newest first — collected September 26, 2024 to May 19, 2026. The summary above covers all 12.
47 results from the 10 samples listed here: 12 detected, 35 not detected. Across the whole record it is 187 of 1,076. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
